Continue displaying storyboard even if fully dimmed in specific circumstances
Closes https://github.com/ppy/osu/issues/9315.
Closes https://github.com/ppy/osu/issues/29867.

Notably, this does nothing about
https://github.com/ppy/osu/issues/25075, but I'm not sure what to do
with that one in the first place.
